Hair Loss on Legs

Causes of hair loss on the leg

When people think of hair loss, also known as alopecia, they are likely to think of losing strands of hair from their heads. While this type of hair loss is the most common, hair can be lost from virtually any part of the body, including the legs.

Leg hair loss is common in both men and women. However, if you notice large amounts of hair falling from your legs or if it occurs suddenly, it may be time to see your doctor.

Causes of hair loss on the legs

Hair loss occurs when individual hairs are shed from the follicles and the follicles do not produce new hairs. As the body ages, the hair on the leg may thin and begin to fall out. This is especially true if hair loss is common in your family.

Alopecia areata, a type of hair loss disorder, is also hereditary. With alopecia areata, your immune system attacks your own cells that contribute to hair growth. Alopecia areata most commonly affect the patched scalp. Hair loss throughout the body is called universal alopecia. Anterolateral leg alopecia refers to hair loss on the legs that is found mainly on the front and external sides.

Leg hair loss can be related to the following symptoms and conditions:

·         Bad circulation

·         Peripheral arterial disease (PAD)

·         Diabetes, which is a risk factor for PAD

·         Chronic eczema, psoriasis, or other skin conditions

·         Thyroid conditions, especially hypothyroidism

·         Fungal infections

·         Hair follicle infections

·         Severe folliculitis

·         Hormonal changes, such as those that occur during pregnancy and menopause

·         Pituitary gland disorders

Other possible causes of hair loss on the legs include:

·         Nutritional deficiencies, such as iron, zinc, and vitamin D

·         Steroid use

·         High levels of stress

·         Wearing tight pants or socks

·         Prescription medications, such as blood thinners

·         Recent illness or major surgery

The causes of hair loss on the legs are numerous. If any underlying condition is causing hair loss on your legs, it is also likely that you are losing hair on other parts of your body as well. Some exceptions are specific leg conditions, such as PAD on the legs or friction from the clothing you are wearing.

Hair loss on legs in men and women

Leg hair loss may occur in both men and women. However, alopecia or hair loss on the leg is believed to be more common in men.
